Very niceee! 2" cam lock on feed end?

You know it

Nice build!  

You may need to make the jet smaller for proper suction and a way to stop over sized material from entering the nozzle.

Excellent work I have to say.             HERE HERE

This was just tack welded and was being finished, we've got some ideas for blocking oversized materials and still need to put cam locks on, we didn't downsize like your (hydro force) does but we will see how it works, either way a lot better than spending $350

nice build . I made my 3"  and reduced the jet to 7/8" and found I only had 2 " of vacuum so took it apart and
went to 1 1/2 " .that brought the vacuum up to 9" of mercury . I used a automotive vacuum gauge for testing
engine and fuel pump presures .hope this of use to you .

Heres updated pics of the nozzle finished, we haven't tested it yet but should work great! thanks for the info nuggetsucker we're running 3" down to 1.25", don't worry about the powder coat job, the guy at the shop thought that would be funny!!!!

I need some expert knowledge!!!
Took the suction nozzle out this past weekend and needless to say it SUCKED!(no pun intended)
We have a pump running 9000GPH(tested an confirmed)
-2" feed (20ft)
-3" return (15ft)

We have LITTLE if not ZERO suction once we drop below the level of the highbanker.
It is really weird, because if we pick the nozzle up out of the hole, and keep it LEVEL, or above the highbanker it has VERY GOOD suction. I dont know what it is??
Could the 1.25" JET at the front of the nozzle be TOO big, thus not creating enough suction from the venturi? Or, could it be 3" is just too large? Here are a few pictures to show what I am talking about


And a few from our trip

9000 gph is fine...what pressure will it develop @ the venturi? I think if you don't have a high pressure pump, that could be the problem...does it feed the gravel good @ highbanker level? Or just have good suction (on your hand?)
